PDF is not an editable format, it is a finished published format.

LibreOffice is not a PDF editor/viewer.

But if you need a PDF page with high fidelity to published form, insert (one page at a time) as an image on a LibreOffice document (using the Chromium projects pdfium PDF parser). For now you need to split any multi-page PDF apart externally to LibreOffice.

Otherwise if you choose to filter import PDF to LibreOffice, i.e. Open it, each element of the PDF, text runs and graphics, is individually parsed by poppler project libs and written by cairo libs to document canvas as new drawing objects. 

Into the Draw module by default but filters are available to bring PDF elements into Writer or Impress.

The resulting ODF documents can be manipulated saved and printed as needed.

The PDF is not directly modified, but hangs around in the document cache (for use when printing some element by reference).
